“…This method was proposed by Bejan [26,27]. In recent years, many papers have been published on the entropy generation in thermal system [28][29][30][31][32][33][34][35]. Makinde and Eegunjobi [36] have made an analysis of inherent irreversibility in a variable viscosity MHD generalized Couette flow with permeable walls.…”

This paper is concerned with the entropy generation in a magnetohydrodynamic (MHD) pseudo-plastic nanofluid flow through a porous channel with convective heating. Three different types of nanoparticles, namely copper, aluminum oxide and titanium dioxide are considered with pseudo-plastic carboxymethyl cellulose (CMC)-water used as base fluids. The governing equations are solved numerically by shooting technique coupled with Runge-Kutta scheme. The effects of the pertinent parameters on the fluid velocity, temperature, entropy generation, Bejan number as well as the shear stresses at the channel walls are presented graphically and analyzed in detail. It is possible to determine optimum values of magnetic parameter, power-law index, Eckert number and Boit number which lead to a minimum entropy generation rate. ª 2015 Production and hosting by Elsevier B.V. on behalf of Faculty of Engineering, Alexandria University.

“…An abundant amount of literature is available relating to thermodynamic analysis of flow in a channel with different geometry and physical configurations [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. Sahin and Yilbas [37] discussed the entropy generation effects in the flow between parallel plates channel where the fluid flow is due to bidirectional compression of the upper plate.…”

Magnetohydrodynamic (MHD) nanofluid flow considered to be steady, incompressible and electrically conducting, flows through permeable plates in the presence of convective heating, models as a system of nonlinear partial differential equations which are solved analytically by the Differential Transform Method (DTM). Copper, aluminum oxide and titanium dioxide nanoparticles are considered with Carboxyl Methyl Cellulose (CMC)-water as the base fluid. Variation of the effects of pertinent parameters on fluid velocity and temperature is analyzed parametrically. Verification between analytical (DTM) and numerical (fourth-order Runge-Kutta scheme) results and previous published research is shown to be quite agreeable. The temperature of Cu-water is found to be low in comparison with 2 3Al O -water and 2TiO -water which is reasonable for high thermal conductivity of copper. Furthermore increasing the volume fraction of nanoparticles causes enhancement of thermal conductivity and decrease in temperature.
